Tungaloy Adds Self-Centering Drill Heads to the DrillMeister Indexable Drill Head Line

03. Dec. 2018.

Iwaki, December 2018 – Tungaloy’s DrillMeister indexable head drill line now includes the DMC style drill head that features a self-centering chisel edge profile in a new coating grade designed to boost indexable drilling performance.

DrillMeister allows easy and prompt indexing of the drill head thanks to an innovative self-clamping mechanism, which eliminates the need to remove the drill body from the spindle for tool changeover or to re-adjust the tool overhang. Fast index with high repeatability significantly improves machine uptime and productivity.

The new DMC drill head incorporates a center-point chisel edge geometry which self-centers to provide accurate hole diameter and circularity. In addition, the new drill head features a double margin design to stabilize the drill during hole making processes, improving hole surface finish and straightness.

The new drill head is available in AH9130. It is a new coating grade specifically engineered for drilling applications, featuring nanoscale multilayered structure coating based on three primary layers. This new coating technology provides an optimal combination of resistance to such physical and chemical stresses as wear, fracture, oxidation, builtup-edge, and delamination, all of which are vital to ensure long tool life for successful holemaking processes. This expansion to DrillMeister further contributes to improvement of hole accuracy, tool life, as well as economy in every hole making operation.
